Table - best surf conditions forecast for Jaconé over the next 16 days.
Alright, let me break it down for you in feet and knots, just how we talk.
The first few days are a mixed bag. Tuesday the 7th starts clean with 5-foot surf from the SSE, glassy conditions, and moderate wave energy (734). Water temp’s about average for the season. But the afternoon goes to hell with a strong onshore wind.
Wednesday the 8th and Thursday the 9th are skunks. Onshore winds and marginal conditions. Thursday morning is glassy but the swell is weak and short period.
Friday the 10th is where it’s at. Morning brings clean 3-foot SE swell with a long 14-second period and light offshore wind. That’s a proper groundswell, good shape. Wave energy is moderate (478). The afternoon gets even better – cross-offshore wind and very good conditions (550 energy). That’s a session to mark.
Saturday the 11th is blown out. Sunday the 12th morning is glassy again with clean 3-foot SE swell (12-second period, 407 energy). Nice, small, clean session for a longboard.
The big standout is Monday the 13th. Morning delivers a strong S swell, hitting 6 feet with a 12-second period. Combined energy is a massive 1131. That’s a powerful, solid swell. With light cross-offshore NNW wind, this is an excellent window for experienced surfers. That’s the biggest, best-structured swell of the whole forecast. Beginners should skip this one. Afternoon still has 6-footers but goes onshore, so hit it early.
From the 14th through the 16th, it’s small, weak, and wind-affected. Thursday the 16th morning has some clean 3-foot SSE swell but it’s very weak (263 energy). Not worth the paddle.
Then there’s a dry spell from the 17th to the 20th. Swells are tiny, period is short, and winds are either too strong or onshore. A proper lull for about four days.
Tuesday the 21st gives a surprise: a clean, moderate offshore morning with 5-foot ENE swell, but a short 8-second period. Combined energy is 410. It’s choppy and short period, but after a flat week, it’s something to ride.
After that, it’s back to tiny, weak waves and strong winds through the 22nd. A 2-foot long-period SSW swell shows up but it’s just too small to surf.
So, for the whole 16 days, the two true standouts are Friday morning, July 10th for a clean, long-period glassy session, and Monday morning, July 13th for the biggest, most powerful swell of the run. Get out early for that one.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
